IMPROVEMENT IN SWITCl-IING CAR-TRUCKS,

VSpecification forming part of Letters Patent No. 43,353, dated'Jnne 28,1864.

To all whom, it may concern:

Be it known that I, JosEPH E. TYNAN, of

Paterson, Passaic county, and State of New Jersey, have invented a newand Improved Sel tSwitching` Oar-Truck for City Railways; and I dodeclare that the fol'owing is a. full and exact description thereof,reference being had to the accompanying drawin,s and letters ofreference marked thereon.

The nature of my invention consists in the switching ot'city-railway'cars around curves or onto sidings without the aid of aswitch or switch tender, the same being accomplished by means ot' alever, to be hereinafter more particularly described, which the driveror conductor presses with his foot on approaching a curve or siding overwhich he wishes to carry his car.

rlhe following description will show theconstruction and operation ot'my invention.

Figure l represents the invention applied to an ordinary city-railwaycar, in which A represents the self-switching apparatus, a forkedshapedlever extending on each side ot' the wheel. (Shown by the dotted lines.)G is the fulcrurn on which the lever works, which when not in use isthrown up clear of the track by means of a spring, D. This lever isoperated by the bent lever E, a part of which projects above theplatform of the car, whch may be depressed bythe driver placing his footupon it, when the guide portion of the lever will fall outside the rail,and if near a curve the car will be carried in its direction.

Fig. 2 represents a vertical view of the truck, showin g themannerinwhich the forkeds'iaped lever is applied, the short arm of thelork on the inside of thevvheel serving the purpose of distributing thestrain or pressure upon the outer arm ofthe fork.

Fig. 3 represents the truck about passing a curve on the ordinarycity-railroad track, f. The lever A, being thrown down, is representedas in operation, confining the wheel to the track, and thereforefollowing the curve.

Fig. 4 is an end view of the forked lever applied to the wheel, showingthe manner in which it acts as a substitute for a doubletianged wheel,and thus confining the wheel to the track.

What I claim as my invention, and desire to secure by Letters Patent, is

' The lever A,orits equivalent, as shown and described, when applied tocityerailway car trucks for the purpose of switching such cars from astraight tl ack around curves or onto other tracks or sidings.
